Step-by-step explanation:
b=a-80
c=b-61
c=a-141
a+b+c=3a-221=430
3a=651
a=217 & b =137 & c=76

Answer:
I must sell more than 318 copies so my revenue is greater than my costs
Step-by-step explanation:
The cost function (C(x)) is divided in two: fixed costs and variable costs. In this case, we have both, the fixed costs are $3,500 that I will spent on advertising and the variable cost is the print cost that depends on the number of books i want to print. The cost function is:
C(x)= $3,500+$4x
The revenue function depends on the number of books I sell:
R(x)= $15x
If i want to know how many books I should sell to have a greater revenue than cost i must solve this inequality:
Revenue (R(x))>Cost (C(x))
$15x>$3,500+$4x
$15x-$4x>$3,500
$11x>$3,500
x>$3,500/$11
x> 318,18
I must sell more than 318 copies so my revenue is greater than my costs
